BRAKE-BLOCK.

SPECIFICATION forming part of Letters Patent No. 332,693, dated December15, 1885.

Application filed May 10, 1884.

To all whom it may concern:

Be it known that I, ROBERT S. C. HERR- MAN, a citizen of the UnitedStates, residing at Gardenville, in the county of Baltimore and State ofMaryland, have invented certain new and useful Improvements inBrake-Blocks; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in thel art to which it appertains to make and use the same. I

My invention relates to improvements in brake-blocks for wagons,carriages, and other kinds of vehicles; and the object is to produce abrake block that is very simple in its construction, that can be easilyapplied to old as well as new vehicles, is not liable to get out oforder, that has a neat appearance, and yet by it great power can beexerted, as it is very strong and not liable to break, and in which thewooden filling-piece can be easily removed when worn out.

rlhe invention consists in the construction and arrangement of parts, aswill be more fully described hereinafter, and more specifically pointedout in the claims, reference being had to the accompanying drawings andthe letters of reference marked thereon.

Like letters indicate similar parts in the different gures ofthedrawings, in which- Figure l represents a side elevation of my improvedbrake-block. Fig. 2 is a face View ofthe same. Fig. 3 is a rear viewofthe same. Fig. 4 is a front view of the iron brakeshoe with the woodenller removed. Fig. 5 is a vertical cross-section ofthe brake-block- Fig.6 is a vertical cross-section of the brake-shoe.

In the drawings, A re )resents a brakeshoe, made of cast-iron or ot ersuitable material, and consists of rear part, a, to which the flanges orears b are cast or otherwise lirmly secured. The part a has atransverseangular projection, c, upon which the wooden filling-piece B issupported. This lling-piece snugly tits onto said projection and fillsup the space between the ears. lt is faced with a facing-piece, C,

that is secured to the filler bythe boltsd. This facing-piece may bemade of metal, leat-her, rubber, or any other suitable material, and

can be readily replaced by a new piece when u worn out. vrlhefilling-piece Bis held in place by a set-screw, e, which passes throughone of the ears, as seen in Fig. 2. The brake-block is secured to theordinary brake-bar, D, the ends of which pass through the rear part, a,and is held in place by a nut,f. One end only of the brakebar is shownin the drawings.

When it is desired to remove the wooden lling-piece, it is onlynecessary to take out the set-screw e, and by slightly tapping the pieceB on its lower end it can be removed from the projection c and taken outfor repairs or for substituting for it a new one.

The facing-piece can be readily taken off by removing the bolts d, andreplaced by a new one when worn out.

It will be readily seen that the ears of the brakc-shoeprotectthesidesofthe filling-piece, and it cannot split, and leven it' itshould split it cannot become lost.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. A brake-block consisting of a brake-shoe having ears b, which protectthe sides of the rubber B, provided with a facing-piece, and said rubberheld in place by a setscrew and supported on a projection, c, which alsoreceives the thrust, all constructed and arranged substantially asspecilied.

2. The combination of a brake-shoe, A, having ears b and angularprojection c, with a rubber, B, having facing-piece C, and held in placeby a set-screw, e, and attached to the brakebar D, all constructed andarranged substantially as and for the purpose set forth.

In testimony whereofl a'iix my signature in presence of two witnesses.

ROBERT S. C. HERRMAN.
